Slots odds are never 100% in your favor, but with these tips, you’ll be able to maximize your chances of winning.

Slot Machine Mechanics

Slot machines are deceptively simple. At first glance, it may seem like all you have to do is pull the lever or press a button and hope for three matching symbols in a row. However, there’s much more happening behind the scenes that influences your odds of winning.

Regulation through RNGs

At the heart of every slot machine is a random number generator (RNG). This computer program uses complex algorithms to generate random numbers that determine a sequence of symbols on your slot machine. When you hit the “spin” button or pull the lever, the RNG stops at a specific number, which corresponds to a combination of symbols on the reels.

It’s important to note that there are many different types of RNGs. The most commonly used one in land-based and online casinos is PRNGs. PRNGs, also called pseudo-random number generators, use mathematical formulas that are computer-based to produce random numbers. On the other hand, TRNGs (true random number generators) rely on the environment to create random odds. TRNGs, therefore, are not used on slot machines.

Casinos need to be regulated by certain government bodies to operate. These bodies often require casinos to use RNGs (both online and in person) to ensure fairness and prevent cheating. Using an RNG means random numbers are generated automatically, and players can continue playing without interruptions.


If you want to sound like a pro, one of the first words you need to add to your casino vocabulary is reels! Reels are the columns on a slot machine that contain the symbols or numbers that determine whether you win or not. Depending on the slot game, each reel can have anywhere from 3 to 9 symbols, and even wild symbols (more on this later).

3 Reel vs 5 Reel Slots

3 Reel Slots vs 5 Reel Slots

The number of reels plays a big role in influencing how a player feels when they play. Traditional slot machines usually have 3 reels, which might make players feel nostalgic and give a more retro experience. Think fruits, candies, and traditional “Lucky 7s.”

On the other hand, modern slot machines normally have 5 reels that have an overall theme and more bells and whistles. For instance, 5-reel slots usually offer more bonus features, better graphics, and more exciting gameplay! Of course, whether a slot is 5-wheel or 3-wheel won’t determine your win rate. This is all left up to the RNGs!


Slot Machines Symbols

Symbols vary widely from game to game, but there are some that you’ll find in almost every slot machine. These include:

  • Wild symbols: These symbols can substitute for any other symbol on the reel, increasing your chances of winning.
  • Scatter symbols: These symbols can trigger special bonus rounds or free spins if a certain number appears on the reels.
  • Multiplier symbols: These symbols increase your winnings by a predetermined amount if they appear on the reels during a winning combination.

Other common symbols include high-value card suits like hearts, diamonds, spades, and clubs, as well as themed symbols based on the game’s theme. For example, a pirate-themed slot might have treasure chests, swords, and ships as its main symbols.

Symbols not only add to the overall theme and aesthetic of the game, but they also play a crucial role in determining your winnings. Unfortunately, you can never predict what symbols will appear on your reels. But, keeping an eye out for special symbols can make the game all the more exciting!


Slot Machine Paylines Paylines are by far one of the most important aspects of slot machines. These are the lines that determine how and when you’ll win money. In traditional 3-reel slots, paylines were usually just horizontal lines across the middle of the reels. However, in modern 5-reel slots, paylines can be vertical, diagonal, or even zigzagged.

The more paylines a slot machine has, the higher your chances of winning! This is because with more paylines come more opportunities for symbols to land on them and create winning combinations.

Decoding Slot Odds

Slot odds are a crucial factor to consider when playing slot games and when choosing the winning slot machine. These odds determine how likely you are to win and how much you could potentially win. They are often displayed as the RTP (Return to Player) percentage, which indicates how much of your bet will be returned to you over time. Volatility also plays a role in slot odds, with high volatility slots having less frequent but higher payouts, and low volatility slots having more frequent but smaller payouts.

While we’re going to discuss RTP and Volatility in a second, it’s first important to understand how slot odds work and probability basics. Knowing these fundamentals can help you make more informed decisions when playing slot games and managing your bankroll.

What Are Slot Odds?

Slot machine odds are essentially the chances of winning. They are determined by a random number generator (RNG) that, as we discussed, is built into every single slot game and constantly cycles through thousands of numbers choosing one that determines your reels. Numbers generated also correspond to the symbols on the reels, determining which symbols will appear and thus, if you win or not.

As mentioned before, slot odds can be displayed as RTP or volatility, which give a general idea of your chances of winning and how much you could potentially win. However, it’s also important to remember that slot machines are unpredictable and no strategy or system can guarantee a win.

Probability Basics

The win probability of a slot machine is completely random. Unlike casino games where skills and strategies can improve your odds of winning, such as table games and card games, slots are purely based on chance. There’s no real way to predict the outcome of each spin. When talking about slot odds, it’s important to understand the concept of independent events.

Each spin on a slot machine is an independent event, meaning that previous spins do not affect the outcome of future spins. This means that each spin has the same chances of winning regardless of how many times you have played before.

Sure, higher RTP and volatility might impact your overall odds of winning, but with each spin being an independent event, it’s all about luck and chance. Many players think that the more they play on a certain machine, the more likely they are to win. This is known as the gambler’s fallacy and it’s important to remember that each spin is a new, independent event.

Return to Player (RTP) Explained

Understanding RTP in Slots RTP (return to player) is, by far, the most common way of displaying slot odds. It represents the percentage of all wagered money that a slot will pay back to players over time. For example, if a slot has an RTP of 95%, it means that for every $100 wagered, the machine is expected to pay out $95 in winnings.

It’s important to note that this is calculated over a long period of time and does not guarantee individual wins. In fact, you could play for hours without getting close to the advertised RTP!

RTP Ranges – In Person and Online Slot Games

RTP can vary greatly among different slots, with some having higher percentages than others. In general, lower RTP slots range from 88%-92%, while higher RTP odds can range from 95%-99%. However, these ranges are not set in stone and can vary depending on the specific slot machine.

When choosing a slot to play, it’s always recommended to look for ones with higher RTP percentages. While this doesn’t guarantee you will win, it does give you slightly better odds of getting some of your money back over time.

Is a 100% RTP Possible?

One thing you might notice is that there is no slot with a 100% RTP. This is because casinos are businesses, and they need to make a profit to stay in operation. If a slot had a 100% RTP, it means that players would win every time and the casino would lose money. Therefore, casinos set their machines with an expected return percentage that ensures they make a profit.

What Is House Edge?

House edge refers to the percentage of a player’s bet that the casino expects to keep as profit. Even online casino platforms have a house edge. Some shady casinos have lower RTP slots to purposefully give them bigger profits, but most reputable casinos will have a mix between high and low RTP slot machines, progressive jackpot slots, and more, so you have a varied chance of hitting winning combinations!

The Impact of Volatility

Payouts are not only influenced by RTP, but also volatility. Slots volatility refers to how often and how much a slot machine pays. A high volatility slot will have fewer but larger wins, while a low volatility slot will have more frequent but smaller wins.

Choosing Volatility

High volatility slots are better for players looking for big payouts and who are willing to take risks, while low volatility slots are better for players who want to play slots longer and potentially win more frequently, but with smaller amounts.

It’s important to note that RTP and volatility are not necessarily related. A high RTP slot could still have high or low volatility, and vice versa. Most online slots will have information available about their volatility, so you can choose the type that best suits your playing style and goals.

In addition, it’s important to know that volatility still doesn’t determine your overall luck when playing. Even a low volatility slot could give you a losing streak, and a high volatility slot could give you a big win on your first spin. It’s all determined by a random number generator, so it’s important to always play slot machines within your means and not chase losses or get too caught up in the potential of a big payout!

Tips for Slot Success

Based on our experience playing slots, reviewing slots, and speaking with other casino players, we know one thing: there’s no guaranteed way to win at slots. However, there are some tips that can help increase your chances of success and make your slot experience fun-packed rather than stressful! Take a look at some of our tips for slot success below.

Selecting the Best Slot Machines

If you’re looking to maximize your chances of winning and want the best slot machine odds, there are a few factors you should consider when selecting a slot machine. From our experience, many people choose casino games and online slots based on theme alone. But, a skilled player knows how to factor in RTP, bankroll management, and personal goals when choosing a particular slot.

Ask About RTP

As we discussed earlier, the RTP is an important factor to consider when choosing a slot machine. Look for slots with higher RTPs (95% or above), as they have better odds of giving you returns over time. If you play online slots, you usually have this RTP information available. If you’re visiting a casino in person, locals and regulars can typically give you advice on which slot machines have higher RTPs (and other casino game tips on the casino floor, for that matter).


Another factor to consider is the amount of bonuses and paylines available. The more bonuses and paylines a slot has, the higher your chances of winning. Don’t be afraid to explore different slot machines and find ones that have a good balance of RTP, bonuses, and paylines! You’ll find that using these factors is much more important than the theme!

Effective Bankroll Management

Managing your money effectively is crucial if you want to have a successful gaming experience. It’s important to set a budget for yourself before starting your slot session. This will help you avoid overspending. While setting a budget is perhaps the most important aspect of bankroll management, there are a few other tips you should follow to make sure your money lasts longer.

For instance, you can divide your money up and spend it on different slots so you have more chances to explore different machines. That way you won’t have to take out more funds if you see another slot machine that catches your eye after you’ve been cleaned out.

Another great tip for managing your bankroll is to set a win and loss limit. Decide on a certain amount of money you’re comfortable with losing, and if you hit that limit, stop playing. Similarly, if you reach a certain amount of winnings, take some time to cash out and enjoy your profits. Don’t be tempted to take all of your winnings and keep playing, and instead, only spend a portion of your profits on future slot sessions.

Busting Slot Machine Odds Myths

Common Slot Machine Odds Myths

Despite the many tips and advice we give players, we know that myths still run rampant in the slot lovers community. To help you break free from these common misconceptions, we’ve compiled a list of the top slot myths and debunked them for you!

Myth: Slot machines pay out at certain times.

Fact: Slot machines use random number generators (RNG) to determine results, meaning that each spin is completely independent and has an equal chance of winning or losing regardless of previous spins. They don’t pay out every hour, 15 minutes, 10 minutes, or other specific time intervals.

Myth: Slots that haven’t paid out in a while are due for a big win.

Fact: Similar to the first myth, there is no pattern or cycle for when a slot machine will pay out. Each spin is determined randomly by the RNG, and previous spins have no impact on future ones. Some players will go so far as to hold a machine even if they step away because they believe it’s “due” for a win, but this is simply not true!

What About Progressive Jackpots?

Some people think progressive slots are the exception to this rule, since the jackpot prize grows overtime. However, just because the prize hasn’t been won yet, does not mean it will be won by you no matter how many spins have happened previously.

Myth: Playing at certain times or days increases your chances of winning.

Fact: Similar to the previous myths, there is no specific time or day that will increase your chances of winning at slots. However, tournaments can offer better bonuses during certain times, but this is due to the structure of the tournament and not the slot itself.

Myth: The more you bet, the higher your chances of winning.

Fact: While it’s true that betting a higher amount can result in larger payouts, especially if you hit a multiplier, it doesn’t necessarily increase your chances of winning. Each spin still has an equal chance regardless of the bet size. It’s important to always bet within your budget and never chase losses by increasing your bets.

Myth: Lucky tokens or rituals can help you win slots.

Fact: This is probably one of the most common misconceptions about slot machines. While it may bring some players comfort to have a lucky token or perform a ritual before playing online slots or in person slots, it has no impact on the outcome of either game.

Advanced Slot Strategies

Two of the best ways to truly increase your bankroll are to compete in slots and utilize bonus features. But why the hype?

Competing in Slot Tournaments

Slot tournaments are competitions between players to see who can win the most on a specific slot game in a given timeframe, who can have the most spins, or who can achieve the highest score. These tournaments often have a small entry fee and offer big prizes like cash or free spins. Other tournaments involve using progressive jackpot slots, which offer big payouts to players as past players pool together money but don’t win.

By participating in slot tournaments, you not only get to enjoy your favorite games but also have a chance to win big without risking too much of your own money. Check to see which tournaments fit your bankroll. For instance, some opt-in fees may cost $0.10 per spin, while others may be higher or lower.

When participating in these tournaments, don’t get discouraged if high rollers take the top spot in the leaderboard. At the end of the day, it’s all about luck and anyone can be the winner. Just remember to always gamble responsibly and within your means!

Utilizing Bonus Features for Online Slots and In-Person Slots

One of the advantages of playing more modern slots is the availability of various bonus features that can help increase your chances of winning. These can include free spins, multipliers, wild symbols, and more. Knowing how these features work and when they are triggered can greatly enhance your gameplay and potentially lead to bigger payouts.

Sure, you can’t control when these features will appear, but taking advantage of bonus features when they do appear is crucial. For example, if you manage to trigger free spins or a bonus round, make sure to spin the wheel and watch your wins stack up!

Another way to leverage bonus features is by keeping an eye out for them when choosing which online slot games to play. Look for games with a high percentage of bonus rounds or features coupled with high RTP (return to player) rates. This can increase your chances of hitting a big win!


Playing slot machines can be incredibly fun and exhilarating, but it’s important to remember that luck plays a huge role in these games. Always gamble responsibly, set limits for yourself, and have fun while playing! We encourage you to explore different slots while keeping a limit for yourself. You can use our tips, such as choosing slots with higher RTPs and varying volatility, exploring bonuses, and setting limits, to enhance your gambling experience. Remember, playing slots should be a form of entertainment, not a way to make money.

In fact, if you feel you need to constantly chase after your losses, feel anxiety while playing, or have difficulty stopping, it may be a sign of problem gambling. In such cases, seek help and support from trusted resources like Gamblers Anonymous or 1-800-Gambler.

We hope this guide has provided valuable insights into the world of slot machines and how to make the most out of your experience. Whether you play at an online casino or visit Vegas, remember to gamble responsibly and have fun! Happy spinning!


What slot machine has the best odds of winning?

The slot machine with the best odds of winning is Dim Sum Prize, which has a 97.18% RTP and medium volatility. Other high RTP slots include The Angler (97.10%), Monster Pop (97.07%), and Jack Hammer (96.96%). These slots offer better chances of winning due to their high RTP rates.

How do you pick a winning slot machine?

To pick a winning slot machine, look for games with a high RTP (Return to Player). RTP indicates the percentage of wagered money a slot will pay back to players over time. Choose slot machines with an RTP of 90% or higher for better winning odds.

How to tell a slot machine is going to hit?

You cannot predict when a modern slot machine will hit because each spin’s outcome is determined randomly. Regardless of previous spins, the probability of winning remains consistent. Though some believe otherwise, slot machine results are not influenced by prior spins.
